"BURNER FoR LIQUI D- FUEL.

SPECIFICATION forming part of Letters Patent 9. 728,355, dated May 19, 1903. i

1 Application filed May 15 1902.

To all whom it may concern:

Be it known that-we,NIO0LAs BECK andv RENE DIOR, engineers, citizens of the Republie of France, and'residents offiSt. Nicolas Usines, Granville,France, have invented new and useful Improvements in Burners for. Liquid Fuel, of which the following is a speci- .fication. 1

to be mixed can be regulated as required, and" that the flame can be extinguished very, easily. v In the accompanying drawings .the improved burner is shown as appliedto a lamp for lighting an incandescent mantle. V

Figure 1 is vertical section throughthe burner. Fig. 2 is a'sect-ion on line A B of Fig. 1.

The burner, which is hereinafter only described as used in connection with alamp, can be used equally well for heating purposes.

The burner consists of the wick-tube 1, which is air-tightly mounted in the baseplate 2 of the frame and projects into the basin 3 for the liquid fuel. Thewick-tube lis covered by a gas-tube 4, the lower end of which is screwed or otherwise fastened onthe base-plate 2, and the upper end of which is hermetically closed by a cap 5. This cap 5 is air-tightly connected with the gas-tube 4 by screw-threads or in any other suitable manner. At the bottom end of the air-tube outlets 6 for the escape of the gas are provided,'which open into the gas-chamber 7, which is formed at the bottom end outside the gas-tube 4 by means of a conical shield 8. This conical shield 8 becomes narrower toward the top and leads up to somewhat below the middle of the gas-tube 4:. The upper rim of the conical shield 8 nearly touches the outer wall of the gas-tube, so that a small ring-shaped opening 9 for the escape of the gases is provided. The conical shield 8-may Serial tra-io'msa. (No modem" the top plate is perforated to allow the eswell as the upperpart of the gas-tube4,is

end of the wick-tube 1. This outer shell has "holes 11' at the bottom, which serve 'asinlets for the air The free space 12 betweenthe. ouler'shell 10 and the gas-tube; above the top end of the conical shield 8 serves as a mixin gchamber for the gas and the outer air and ,is covered at the top bya plate 13, which has perforations 14 for the escape of the mix ture of gas and air.

If the burner is to be used for lighting pur- ,poses'in connection with an incandescent mantle, the incandescent mantle15 is suspended in the'well-known manner, so that its bottom edge surrounds the mixing-chamber. V

In the'wall of-the conical shield San outlet 17 is provided, which is closed' by means of ascrew-valve 16, tobeactuated by a handwheel 18 or in any other suitablemanner,

the top plate 13 'of On the outer shell 10 a cup 19 is arranged,

which serves forthe purpose of previously heating the burner. "The burner works in, the following manner: To start the operation-of the burner,

the cup 19 is filled with alcohol, the flame of which surrounds the upper part of the burner, which is thereby heated and causes the alcohol or other liquid fuel with which the wick ;is soaked to evaporate at the upper end of fthe'gas-tube 4. The gaseous vapors fill the gas-tube 4 and the gas-chamber 7, formed by i the conical shield 8, and escape through the openings 9 at the top end of the conical shield "mixing-chamber l2 thegaseousvapors mix the gases ready for lighting flow out through 8 and e'n'terthe mixing-chamber 12. In the the perforations 14 in the top plate 13 of the outer shell after they have ignited at the flame of the cup 19. The burn-eris now'in operation and the evaporation and combustion are automatically sustained.

The gallery 20 of the chimney 21 can be provided with adjustable openings to regulate the admittance of the air to the burner.

To extinguish the flame, it is only necessary to open the screw-valve 16, so that the escape 22 in the valve is opened, whereupon the gas contained in the gas-chamber 7 escapes before getting to the mixing-chamber 12, so that the flame is extinguished for want of fuel.

Instead of a circular gas-space, as provided by the gas-tube 4 hereinbefore described, several gas-tubes can be used branching off from the cap 5, arranged over the top end of the wick-tube 1.

Having fully described our in vention, What we claim, and desire to secure by Letters Patout, is-

A burner for liquid fue1alcohol, benzol and the like-comprising in combination with the wick-tube, a gas-tube inclosing the wicktube, acap at the top of the gas-tube connected with the same, a conical shield at the bottom of the gas-tube, extending upward to somewhat below the middle of the gas-tube and communicating with the interior of the same by means of openings provided at the bottom end of the gas-tube, an outer shell with holes for the inlet of air at its bottom surrounding the conical shield of the gas-tube, a perforated plate closing the outer shell at the top and a screwvalve in the Wall of the conical shield opening to the outer air and allowing the extinction of the flame, substantially as described and shown and for the purpose set forth.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
